Application filed September 18, 1923. Seriell No. 663,441.

To all fio/0m 'it may concern.:

Be it known that I, PHiLis MAYOTTE, a citizen of the United States, anda resident yof Escanaba, iii the county of Delta and State of Michigan,have invented a new and Improved Sash Fastener and Lock, of which thefollowingis a. full, clear, and exact description.

-This invention relates to locking mechanisms for windows and the. likeand particularlyto an improved sash fastener and lock wherein the sashis normally maintained locked but the parts are so positioned andarranged that by a slight manipulation, the sash may be readily moved toany desired position.

Another object of the invention is to provide an improved sash fastenerand lock wherein there is provided an improved lockving mechanismadapted to automatically move toa locked position whenever released.

A still further object ofthe invention is to4 provide a sash. lockwherein an improved structureris presented that is comparatively smalland formed to be readily embedded in the window frame at substantiallyany point.

In the accompanying drawing- Figure 1 is an elevation of a window frameand a pair of sashes, certain parts being broken away for better'illustrating the fastener and lock applied thereto.

Figure 2 is an enlarged fragmentary transverse sectional view throughFigure 1, approximately on line 2 2.

Figure 3 is a sectional view through F igure 2, approximately on line 33.

Referring to the accompanying drawing by numerals, 1 indicates a frameof any desired kind which is provided with saslies 2 and 3 of anydesired or preferred kind. Each of these sashes is formed with a cutawayportion 4 adapted to accommodate a rack 5 formed with teeth 6 designedto be continually in inesh with the gear 7. As the sashes 2 and 3 are ofidentical construction and also the locking mechanisms in connectiontherewith are identical, the description of one will apply to both.

As shown particularly in Figures 2 and, the gear 7 and certain otherparts are arf ranged in a casing 8 formed preferably of sheet metal,said casing including an inner plate 9 having an opening l0 throughwhich part of the gear wheel 7 projects. Suitable securing screws 11extend through plate 9 possibly a little of the and through flanges 12,said screws engaging 5% is'rigidly secured tothe frame.

From Figures 1 and 2 it will be noted that the casing S and associatedparts arearh ranged within the frame and that merely the rod 13 extendstherethrough, said rod having a button or enlargement 14 fitting into aSuitable recess l5. rllhe rod 13 is preferably threaded into a centeringpin 16 which is provided with aflange 17 for receiving the spring 18,which'spring surrounds the pin 16. The pin 16 is provided with a roundrestricted connecting portion 19 merging yinto a square portion 20. Thevspring 18and certain other parts are positioned in the bore 21 of thehub/22 of gear wheel 7. They gear `wheel7 is also provided with acentral depression 23 for receiving the Lboss or enlargement 24 ofcasing 8, which boss or en-y largement is formed with a square aperture`25 registering with the square aperture part of the frame 1 wherebythecasing A 26 fo-rined in the gear wheel 7. The spring f 18 normally holdsthe parts in the position shown in Figure 2 whereby the square section20 lits into the square apertures 25 and 26 and, consequently, locks thegear wheel 7 against rotation.. l/Vhen the gear wheel 7 is lockedagainst rotation, it will positively hold the sashin the position inwhich it is at that time and acts as a lock therefor.

If the sash is entirely closed, it'will be locked yclosed or if it ispartially open, it will be locked in. that. position and held againstmovement until the thumfb member or button l14 kis pressed for forcingthe round section 19 into the square aperture 26 whereupon gear wheel 7is released and, consequently, may freely rotate as the sash is movedupwardly or downwardly. As soon as the Vbutton 14 is released, spring 18`will move back to the position shown in' Figure 2 and, consequently,part of the square section 20l will enter the square opening 26 and lockthey gear wheel 7 against rotation and in this manner lock the sashagainst movementl in either direc-tion. It will be noted from Figure 1that the only parts which are seen are the buttons 14 and respectiveracks 5.

What I claim is :v-

1. A window sash fastener and lock` comprising a rack adapted to besecured to a sash, agear wheel meshing with said rack gear teeth 6 onthe iio provided with a con'iparatively long hub formed with a boreextending` almost entirely therethrough 'and With a square aperturemerging into said.b0re,a casing formed with a square aperture inlinewith the square aperture of the gear Wheel, a manually ac tuated rodextendinzfn `axiallythrough said bore and through said apertures, Saidrod being squared to fit said square apertures, Said rod having `alconnecting section adjacent the square part ,of a diameter not greaterthan the greatest diameter of Vthe square part, andia spring acting onsaid manually actuated member forY holding said square sections normallyengaging the square apertures in the casing and gear Wheel, saidmanually actuated member being adapted to be moved mainuillyV so Vthatthe connecting section will t into the square aperture of the gear Wheelwhereby the `gear Wheelrmay rotate the-sash and "rack Yare moved. y f

2. A combinedr sash fastener and' lock,

comprising a rack secured to the sash, a gear meshing V-with said rackprovided vwith a comparatively long hub, said Ahub 4having;r adepression on one face and a bore extending from the opposite facetoward the depression, and a polyrenal-shapedV aperture connecting saidbore and said depression, a .supporting ,member formed with a bossvIitting into said depression, said boss having a polygonal-shapedopeningI of the same shape and size as the polygonal-shaped opening insaid hub, a square reciprocating member ittinginto said /polygonabshapedopenings for locking the hu'b and the casing together7 saidreciprocating member having a' reduced seetion of a diameter not`greater than the smallestdiameter of the polygonalshaped part ot' thereciprocating member vwhereby it may be forced into the polygonal-shapedopening of the hub and therelby permit al rotation ofthe gear Wheel asthe sash is moved Vupwardly and downivardly.
